Gotham City is a problem, don't you agree? But.. what if it moves to Indonesia?

Another night in crime city, the Bat-family is at the Wayne mansion when they receive a news from commissioner if the supervillains escape again from Arkham.. Including Joker.

The Bat Family wasted no time and track the location. When they got there last location the supervillains were seen, it was a dirty and abandoned building, there was nothing there, just a broken looking portal.

In the blink of an eye, The Joker appeared and quickly pulled a lever that made the same portal glow in a very strong blue color.

Before they knew it, they were violently and quickly sucked into a portal and thrown into a place completely different from Gotham.
